Application filed October 4. 1902..

To rtl/, wiz/011e N; 'ntf/.y concern:

Be it known that I, Henna Ecnnnsou, a citizen of the United States,residing atMechanicsville, in the county of Saratoga and State of NewYorlghaveinven ted certain new and useful Improvements inMattress-Filling Machines; and I do hereby declare the 'following to bea full, clear, and exact descrip-` tion of the invention, such as willenable others skilled in the art to which it aiipcrtains to make and usethe same.

Myinventi'on relates to mattress-filling machines, and has for itsvobject to provide a machine, simple and eiiicient in construction,adapted to readily insert filling material evenly and uniformly into amattress-cover. This I accomplish by the means illustratedr in theaccompanying drawings, in which- Figure l is a sectional side elevationof a machine embodying my invention. Fig. 2 is an end elevation of saidmachine. Fig. 3 is a transverse section taken on line 1 l of Fig. 1.Fig. Lisa plan viewof said machine. Fig. 5 is a plan view taken on line2 2 of Fig.

the endsof the cylinder. The cylinder-heads are preferably provided witha sleeve 11, having a threaded outer surface engaging thecylinder-heads, whereby the sleeves may be adjusted relatively to saidheads. An annular packing-flange 12 is arranged between said sleeve andaboss termed on the cylinder-heads and is provided with a-threaded outersurface engaging the th readcd interior of said boss and with a threadedinner surface adapted to engage the thread on the outer surface ot' thesleeve. A chamberA is left between the end of the llan'ge 12 and thecylinder-head, which may be filled with packing material, so as to makea tight joint between said sleeve and cylinder -head 'A bushing 13 isprovided with a threaded outer surface adapted to engage the threadedinterior of the sleeve 11 and form a packingbox with said sleeve.`

The ends of the pistonwrod 9 are connected with reciprocating heads 14,which are adapt# ed to slide ou ways 1.5, preferably mounted upon thelongitudinal bars 4 at the base of the main frame. Connecting-rods 16are pivotally attached at one end to said reciprocating heads and at theother end to toggle-links 17 and 1S. The links 17 are pivotally attachedat their outer ends to the main frame, andthe outer ends of the links 1Sare pivoted to a verticallymovable table 19, loosely mounted upon themain frame. The frame of the table 19 is preferably constructed oflongitudinal bars 20, connected at their ends to transverse bars 2l,which are provided with heads having a sliding.eingegement with thevertical standards l.

'A lever 22, extending horizontally, is secured to the upper end of avertical shaft 23,

havingattaehed to its lower end a horizontally-arranged lever 24, whichis pivotally attached to a valve-stem 25, connected with a D-shapedvalve of ordinary construction arranged within the valve-chamber' andadapted to operate in connection with portholes formed in the cylinder6. Vtlhen the lever 22 is moved inward, the vertical shaft 23 is therebyrotated, giving a correspondingly-rotating movement to the lower lever24, attached to said vertical shaft, which move ment operates thevalve-stein 25, thereby carrying said, valve to the farther end of the4o main frame,preferably in a plane below that 5o 14 is an arm'43',provided on its outer end Co which is pivotaily connected with theupper' valve-chamber and exposing the port-holes of the cylinder nearestto'the vertical shaft 23. y Water under pressure is then allowed to passinto the valve-chamber? through a steed-pipe 26 and, through the openport in Athecylinderback of the piston' when arranged 'as show-nin Fig;1.a; The piston is therebyI moved from the position indicated in Fig.

1 tothe oppositeend'of said cylinder, Where .zo it is stoppedy hy'mea'nsof the inwardly-pro-V jecting endof the sleeve 1l,l secured to thecylinder-head.' Suchmovement ofthe piston causes a correspondingmovement of the reciprocating headsjv14 and connectingLrods 15 16,whichspread thev louter -ends of the links 17 and. 18, andntrhereby raise thetable'19. 'By adjustingthesleeve 1l so as to project more or lesswithin'.the cylinder 6 thestroke of the piston is; regulated and. theupward zo movement ofthe'vl table '19is limited'at the desiredelevation. jv l l A-cylinder 27, largerindia-meterthan the lowercylinder (i, is secured to the'upper portion of the mainframe','preferablyto the c5llceutral llong,itudinal bars'", and isprovided "with the Avalve#chamberv 28, a piston.29,.a

piston-rod 30, cylinder-heads 3l, and a'valvestem 32, similar inconstruction to thev correv spending elements connected with the lower5o cylinder 6, hereinbefore described. Theends' .-of lsaid piston-rodare secured to brackets 33 and, r'which'are mounted upon wayfs 34 andadapted to slide thereon. A series of sheaves-.35 are mounted upon the35 brackets'33 vand 33, and a corresponding series ofsheaves 36 aremounted upon sta- J tionary brackets 37,' attached 'to the outer ends ofthe main frame ofthe machine.- A ,single sheave 3 8 is secured to eachend of said of thesbeaves 3'5 and36. Cables'39 and 39 extend from `thesliding brackets 33 and'33 around each of the sheaves 35 and 36 andaround the single sheave 38, and from thence to a reciprocatingfollower49, 'having a ver tical flange 4l, provided with casters 42,which travel on the inner dangesof the cene. tral longitudinal bars 5".f'

Attached to one of the reciprocating head with a hub or boss, whichengages a rod 44, pivoted on its outer end to thelower end of a leyer45and provided 'with stops 48, arranged-on each side of the arm 43. Thevertical lever 45 is mounted upon a horizontal' shaft 46, which isjournaled'-upon brackets 47, secured to thevertical standards l ofthemain frame. The' horizontal shaft 46 is also provided with avertically-extending lever 49,

valve-stem 32, attached `toa valve arranged within the uppervalve-chamber 28. As the lower pistn-rod 9 is moved to the opposite, endof the cylinder from the position indicatedlin Eiga-1 thelaterally-,extendingarm 43 ofthe reciprocating head 14 comes in conviact with the1 stop 48 ontheleud ot the rod 44 'brackets 33 to theright, drawing the sheaves 35 and 36 on the 'oppositeend ofthe mainfra-me from each other and'winding the cable l39 on lsaid sheavesfandunwinding the cable 39 therefrom. The follower 4Q, attached to thecables 39 and 39, is therebydrawn lengthwise of the main frame. vVheuthe follower 40 is drawn to the loppositeend of the machine from thatshown in vthe drawings,vtl1e sliding bracket33- at theright'of thecylinderis drawn toward the starting-lever22, at-

tached 'to the vertical rodp23. Saidl'sliding bracket 33V is providedwithjatrip-lever 50, which cornesv in :contact with the lever 22 andmoves said level' A outward ,td-the position [originally occupiedbygfsadlever, as indicated in Fig. 4': The'l'ateralmovementof said leverrotates the vertical shaft 23 and the lever'24 at the lowervfend-fotsaid shaft l and draws outward the valve-stein 25, which i" allows thewater to enter' the/reverse end of said cylinder and forces fthepistonahackto the position occupied in'Fig. l1. Iniso doing ,thereciprocating heads '14,[atl'achedto the press downward the outer -endsof the links iston-rod 9 and the connectinffrods com- A 17 and 18 andvpermit the table 19 of the ina-` chine to descend to its originalposition.

and cables connected therewith.- .The fol-V lower 4 secured to saidcables, is 'thereby brought back to its original position -at the rightof themachine.4 All'of the parts will then be in the position indicatedin Fig. 1.

"Racks 5J are secured tothe outer bars of the side sections 52, the endsof whichmove in guides or ways secured tol the upper longitudinal bars 5of themain frame.A Wormshai'ts 54 are journaled in the upper portion ofthe main frame, preferably upon the 1ongitudinal bars 5? in the' centralsection of the top of the main frame, and vsuch vshafts are providedwith worms 55, which engage' the.

, Theupper portion of the main frame is,

toothed racks 53, attached to the side sec tions of said presser-board.The worms 55 are provided with an outer perforation or nut adapted, toengage a wrench or handle, by means of which said worm-shafts may berotated and the outer sections 52 of the presserboard drawn towardoraway from each other,

land thereby adjust the width of said pressera central plate Gat,extending lengthwise of -said bars and secured thereto.

Side plates G6, ext-ending lengthwise of said former, are connected attheir outer edge to brackets 58 and at their inner edge are free tooverlap the central plate 64 of said former. The brackets 58 areprovided with vertical arms having side plates 57 secured thereto andwith horizontal arms having a sliding engagement with the transversebars 60, preferably by means of grooves formed in said transverse bars,corresponding with a projecting rib formed on the side ot' saidhorizontal arms of said brackets and provided with atoothed rack-59. Aworm-shaft 6l extends lengthwise ci the transverse bars 60, and itsouter ends are provided with worms 62, which are adapted to engage theteeth of the racks 5 9. The brackets 58 at each end of said formerarepreferably arranged to engage with opposite sides of the transversebars 60. The worms on the opposite ends of the shafts G1 4o, areprovidedwith right and left hand threads,

respectively, and when rotated draw the side sections of the formertoward or away from each other, thereby adjusting the width of` saiformer to the extent desired. The cuter sid .S of said worms areprovided with an opening or nut of any suitable construction adapted toreceive a wrench or handle, whereby said shafts may be rptated, asalrcadydescribed.

'lVhen the machine is in operation, a suitable qnantity of. the materialto be inserted in a mattress-cover is iii-'st placed within the former.The former is thon placed upon the bed or table 19 of the machine withthe ends of the sides 57 of the fdrmer bearing against the transverseend plates 67, secured to the main frame of the machine, which endplates Serve to close the ends of said former and form, in effect, arectangular frame within which said material is confined. The width ofthe presser-board is then adjusted to correspond with the width f theformer, so that the outcredgcs of the presser-board pass within thcsides of said former and bear di- 'rectly upon the' filling material.The starting-lever 22 is then moved laterally, thereby operating thevalve connected with tho lower cylinder and applying hydraulic pressureto the piston'contained therein. After the piston has traveled thelength of the cylinder it remains stationary, thereby holding the. table19 in its elevated position, with the filling material compressedbetween said table and the presser-board. At the end of the stroke ofthe piston 9 the arm 43 of the reciprocat-` ing head 14 comes in contactwith the stop/18 on the endof the rod 14 and operates the levers 45 and49 and the valve-stem 32 in the manner already described, therebyapplying hydraulic power to the piston in the upper cylinder, whichcauses the piston of said cylinder to travel lengthwise thereof and movethe sliding brackets 33 and 33, which draw the follower 40 lengthwise ofthe machine by means of the cable 39. Such follower forces the materialunderpressure from the table 19 into the mattress-cover, which is firstshirred onto a discharge-hood composed of an upper central section 5l,formed of the continuation of the central plate of the top of themachine, and lower plate 70, secured to the transverse end plates 67.Side sections 7l are secured to the side sections of the top of themachine and adj nstable therewith, so as to make the hood adjustable inwidth to correspond with the Width of the mattress to be illed. When thefollower 40 has traveled the length of the machine and forced thefilling under' pressure through the discharge-hood into themattress-cover, the sliding bracket 33a has been carried toward thestarting-lever 22, and coming in contact with said lever it moves thesame laterally, which reverses the action of the parts connected witht'ne lower piston 9 and allows the table 19 to descend. The reversemovement of said lower pistgn 9, in connection with the arm 43 on thereciprocating head let, reverses the movement of the vertical levers 45and 49 and upper telve-stem 32, which thereby cause the piston of theupper cylind er to travel back the length of said cylinder and give areverse movement tothe sliding brackets 33 and 33, which draws backwardthe follower 40 intoits original position. The machine then stopsautomatically, and theC table 19 and follower 40 will be in the positionindicated in Fig. 1.

By means ofthe construction shown and described herein t-he fillingmaterial may bc equally and evenly compressed and forced under pressureinto a mattress-cover and by nieans of such formers constructedsoparately from the machine. The filling material may be applied to twoor more of such formers at the same time while one former is being usedin the machine. The machine is therefore at no time idle, and no delayis caused inplacing the filling material on the machines and arrangingthe same evenlyand uniformly thereon. As a result a machine of suchconstruction will fill several times more mattresses than can be filledby a machine which must necessarily remain idle while the fillingmaterial is arranged evenly and uni- ICO IIO
